3rd, or maybe 4th times a charm. I've had some weird issues with this lovely quad since I got it, but I pinned this down to some issues with the connections between the motor windings and the motors. iFlight kindly supplied me with some new motors and other parts to basically convert this to the V2 Chimera.
This is also intended as a proper test of my Walksnail gear. Although I've had a set of Walksnail goggles and VTX's, I've only managed to really fly micros successfully - so I was keen to range test this.
You'll also see I was using the RadioMaster Bandit module and BR1 receiver to put an 868Mhz ELRS system on this quad.

Those 21700 Lions have metal casings. They could easily be blocking your video signal...The vtx antenna is ridiculously short. Im using the old twin antenna setups in my quads though. That said, the newer single ant vtx also works well in my planes...🤔😳🇬🇧

Bloody tiny isn't it - weirdly they haven't thought to ever produce new longer ones. The analog antenna that came with this quad was really long as well, that would probably help. Good practice to just make one change at a time, so I'll get onto the Menace antennas first and see what difference they make

​@@CurryKitten I'd replace the quads antenna for a nice long one FIRST...The Lipo power wires are also too close for comfort IMO...Rake angle on the video antenna is designed for a VERY long version too... Because I used to fly WS initially using the standard goggle antennas with no trouble at all. Set the Goggle RF power down at 200mw...This way you'll confirm the real cause....1km at 200mw is easily done.

@@CurryKitten You can buy a set of LHCP true RC antennas. Two omnis, and two patches. Very compact and fit in my case permanently assembled...Worth every penny IMO....🤔😏🇬🇧

Range is definitely improved by a patch on the transmit antenna on the googles. Try patches on both the top antennas. Also get your VTX antenna clear of the battery. By doing that you should also notice an improvement in your gps sat count.
@CurryKitten

Well, those Walksnail antennas are patches... but how well they work is another matter - hence goggles antenna replacements first before I turn my attention to the VTX antenna

I upgraded my Chimera 7 to BF 4.3 and later 4.4. Just take screenshots of the of the PID and filters pages from 4.2.9 and match the PIDs as closely as possible using the sliders on 4.4. Likewise with the filters. Those are the only critical settings you have to get right with the frame. Otherwise you'll get horrible mid to high throttle oscillation, especially with the Gemfan 7040 propellers.

Hey, very nice video, nice to watch. As for WS, replacing the antennas with red cherry from rushfpv helped me. Remember to update the software in VTX and goggles, it also helps a lot.
@CurryKitten

I thought a nice Cheery antenna from Rush would be the trick for the quad, but I'm going to test the change of antennas on the goggles first and then do then VTX antenna afterwards

I recently was treated for my birthday (milestone one :/) a set of the new Walksnail Avatar goggles, so I bought the TX with the diversity antennas to match, installed the setup on an older quad frame with a new speedybee stack to test it out, and was a bit disappointed with the first results such as, very poor range. So I invested on a set of the Menace patch antennas together with a pair of Thrasher omni ones, and Wow, what a difference. At least 4-5 x times the range of the stock antennas, however I did notice when testing the frame of the quad can block the signal, as going away from me to range test with the antennas mounted on the rear signal was really good, until I turned to come home and the picture froze, ended up reversing some of the way back!
@CurryKitten
@CurryKitten Месяц назад
Reversing back home is an inventive workaround - nice one. I don't know why the stock VTX antenna is so soooo short. When you are dealing with a large frame and large lipos, there's just too much to block

@CurryKitten

Yeah - it could be either. But it's always best to try things one-by=one else you are never sure what the fix was if you are doing multiple changes at a time :)

I've never used the stock walksnail antennas(red bird?)I've got twin Menace RC Thrashers or use FOXEER 4+ lollipop 60mm antennas on my vrx on skyzone 04L's and at 25mw i can do 400 metres without breakup no problem at all,i have yet to find a Field thats longer to test max range on 25mw but ive found its as good as Analogue signal wise.

Nice to see the 7” back up and running! Depending on the rating of the li-ion pack it may be worth adding current / amp draw in the OSD. RTH value may potentially burn out the pack if it draws too much!
@CurryKitten
@CurryKitten Месяц назад
I know the long range guys swear by their amp draw and mAh used, but I've never found it particularly accurate in my tests. That said, I haven't tried one for a while. Yep - I need to sort out the rescue mode values so it doesn't use that much throttle

That's weird, everything should be doing so much better on that Chimera7 especially as it's a BNF -- I have a WS Rekon35 that does so much better than that is every way, and that is just using the Walksnail pro single antenna setup Just some thoughts and ideas * There has been reports of High powered ELRS 900Mhz radio stuff affecting Goggles, via the long power lead powering the Goggles. I don't know how your powering your goggles so this is just an idea * Try moving the ELRS antenna to the front of the quad, that will help with separation of Walksnail antenna, and the ELRS -- the design of the antenna cluster at the back of the quad looks terrible considering there is so much room to separate GPS, ELRS and Walksnail antennas, on such a large quad. * Try bottom mount the battery, in that way the Walksnail antenna will be in the clear. * Betaflight 4.3 is terrible as for HD OSD, since there is still so much to sort out, might as well go for Betaflight 4.4 Anyway your Chimera7 not that bad, it's going to give you plenty of material to make interesting videos about 🙂
@CurryKitten
@CurryKitten Месяц назад
I've not heard of the ELRS 900 stuff affecting the goggles, I'll look into it. Trouble is that quad seems to swallow up a little 2.4Ghz antenna, so I was getting big LQ issues flying on 2.4. I might try a bottom mount in comparison - there's slots there so I can easily do it on the fly. I agree that 4.3 is terrible for HD - the situation I have is iFlight only saying they support 4.3 and nothing else. Normally this would be an issue, but when I had it on 4.4 and the motors died, iFlight were like "we told you so" I really don't see the connection, but I'll keep it on 4.3 to apese them for now.

@@CurryKitten just search for HDzero, Crossfire 900Mhz or ELRS 900Mhz and reboot. there is heaps of material on the issue, I just watch an issue where it was affecting signal on analog goggles and I am rather certain that Walksnail would be affected as well -- there is talk that using ferrite beads on the power lead can help. Also wire lengths on the Quad apparently cause issues -- Looks like a lot of stuff to research and make interesting video about ;)

Long time no hear! Yep - it's got this thing called Focus mode, which if the signal gets a bit bad, rather than the latency taking a hit, it just sends the data for the centre of the screen in detail and leaves the sides very blocky. I normally only see it when the signal is very bad, but I had it quite a lot in this flight!

Must be your ariels on you fpv setup, 1.5km was my limit on the walksnail patch’s, so I brought a pair of Truerc x2 patches, and now I can easily get to 7km, felt like they were 100times better than stock.

Coincidently I have the same frame, controller, ELRS and VTX but with INAV, the only difference is the motors, I'm using EMAX ECOIIs. My only issue with this build is the GPS position. It's too close to the powerline which causes interference on the mag. I had to move it to the front with a different mount.
@CurryKitten
@CurryKitten Месяц назад
It can be tricky to get GPS's isolated enough from interference. I was as far as to wrap the line in copper and then solder that copper to a ground. It looked fairly silly, but sats went from zero to actually locking in

I have tested a lot of the Walksnail stuff, different antennas on the quad, different antennas on the goggles V1 and even on the goggles x, and I made it out on full power 700mw up to 1km before it gets blocky... I must say I am really disappointed with that system.... gonna sell all of it and move to DJI goggles2 .. that's a much better system... walksnail still needs some time to catch up to DJI performance.
